The present disclosure relates to electrical connectors, including electrical connectors used for connecting wiring harnesses with power distribution boxes.
Conventional power distribution boxes may include circuit boards with electrical components attached thereto. Typically, the arrangement of the electrical components on the circuit board may be dictated by an arrangement of electrical terminals of a wiring harness electrical connector that connects to the power distribution box. This may result in a less than an efficient or optimized design with some circuit boards.
The present disclosure includes a connector and a power distribution box assembly. In embodiments, a power distribution box assembly may comprise a housing, a circuit board disposed in the housing, a plurality of electrical components attached to the circuit board, and/or a plurality of electrical traces attached to the circuit board. Electrical traces may be configured for electrically connecting the plurality of electrical components to at least one of (i) another electrical component of the plurality of electrical components and (ii) an electronic control unit (ECU). In embodiments, a power distribution box assembly may comprise a wiring harness connector connected to and/or configured for connection with the housing and/or the electrical components. In embodiments, a wiring harness connector may include a connector housing and/or a plurality of connector terminals that may be configured for electrical connection with the plurality of electrical components. In embodiments, the plurality of electrical components may be disposed relative to the circuit board in a manner that minimizes a total amount of the electrical traces.
In embodiments, a method of manufacturing an electrical connector may comprise determining a circuit board layout that minimizes a total amount of electrical traces that electrically connect a plurality of electrical components; designing a layout for terminals of the electrical connector according to the determined circuit board layout; and/or manufacturing the electrical connector according to the designed layout.
Various aspects of this disclosure will become apparent to those skilled in the art from the following detailed description of an embodiment of the present disclosure, when read in light of the accompanying drawings.
Reference will now be made in detail to embodiments of the present disclosure, examples of which are described herein and illustrated in the accompanying drawings. While the disclosure will be described in conjunction with embodiments, it will be understood that they are not intended to limit the disclosure to these embodiments. On the contrary, the disclosure is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the disclosure as defined by appended claims.
Referring to the drawings
In embodiments, such as generally illustrated in
In embodiments, an electrical component 40N may include one or more of fuses, relays, and/or other electrical components. In embodiments, one or more of electrical components 40N may include one or more terminals (e.g., terminals 42N, 44N). Terminals 42N, 44N may be configured for electrically connecting an electrical component 40N to circuit board 20, to another electrical component 40N, and/or to an electrical connector 60. Electrical connector 60 may be referred to herein as wiring harness connector 60, but is not limited to a wiring harness connector.
In embodiments, electrical components 40N may include a first terminal 42N and/or a second terminal 44N. In embodiments, first terminals 42N may be configured to contact circuit board 20 (e.g., make an electrical connection with an electrical trace 50), but may not extend through circuit board 20 and/or may not directly connect with electrical connector 60 (see also, e.g.,
In embodiments, a second terminal 44N of an electrical component 40N may or may not include a substantially similar configuration (e.g., length, width, thickness, etc.) as the first terminal 42N of the electrical component 40N. Second terminals 44N may be configured for insertion into and/or through circuit board 20, which may include having widths 44AN that may correspond to a corresponding aperture 22N in circuit board. For example, and without limitation, width 44A1 of a second terminal 441 may be about the same as corresponding aperture 221 and/or second terminal 441 may be press fit into corresponding aperture 221. In embodiments, second terminal 441 may be configured to extend through circuit board 20 and/or to connect directly to electrical connector 60. For example, and without limitation, some or all of second terminals 44N may be longer than first terminals 42N such that first terminals 42N extend through circuit board 20 sufficiently far to be soldered to circuit board 20 while second terminals 44 extend through circuit board 20 and into electric connector 60 (e.g., first terminal 421 may be shorter than second terminal 441 of electrical component 401).
In embodiments, such as generally illustrated in
In embodiments, it may be desirable to minimize a total amount (e.g., number, length, volume, etc.) of electrical traces 50 on a circuit board 20. A reduced amount of electrical traces 50 may, in some instances, reduce the complexity and/or cost of manufacturing circuit board 20 and/or PDB 10. In embodiments, minimizing a total amount of electrical traces 50 may include determining an arrangement/layout of electrical components 40N on circuit board 20 that minimizes electrical traces 50. In embodiments, a minimized arrangement may include the smallest length, volume, and/or number of traces that still provides desired electrical connections between electrical components 40N. Determining an minimized arrangement may include determining a desired set of electrical components 40N for attaching to circuit board 20 and/or for connecting to a wiring harness connector 60. A desired set of electrical components 40N may include, among other things, fuses and/or relays that may have one or more of a variety shapes, sizes, configurations, and/or electrical characteristics (e.g., current ratings). For example, and without limitation, fuses may include current ratings from 5 amps to 60 amps.
In embodiments, determining a trace minimizing arrangement may, additionally or alternatively, include determining a surface area (e.g., a maximum surface area) of a face/side 24 of circuit board 20 to which electrical components 40N of the desired set may be connected or attached. A minimizing arrangement may be determined according to the desired set of desired electrical components 40N and the surface area of circuit board 20, and/or a list of desired electrical connections. A list of intended or desired connections may specify how electrical components 40N should be connected (e.g., to which other electrical component(s) 40N). For example, and without limitation, electrical components 40N of the desired set may be iteratively arranged relative to the determined surface area and the list of desired electrical connections, and the iteration/arrangement with the lowest total amount of electrical traces 50 may be designated as the minimizing arrangement. In embodiments, iteratively arranging the electrical components 40N may be conducted via a simulation, such as a computer simulation. A simulation may include models of circuit board 20, electrical components 40N, electrical traces 50, and/or electrical connector 60. A computer simulation may be configured to automatically iterate through all possible arrangements, compare the total amount of electrical traces 50 from each arrangement, and/or select a preferred or optimized arrangement (e.g., the arrangement with the lowest total amount of electrical traces 50).
In embodiments, one or more of electrical terminals 40N may include a long side/dimension 40AN and a short side/dimension 40BN. Long side 40AN may be the longest side of an electrical terminal 40N and short side 40BN may be the shortest side of an electrical terminal 40N. As generally illustrated in

In embodiments, such as generally illustrated in
An arrangement that includes electrical components 40N disposed perpendicularly to each other, particularly within the same row and/or column, may be somewhat counterintuitive with respect to conventional designs (see, e.g., conventional design 100 in
In embodiments, after circuit board 20 has been designed (e.g., with a trace minimizing electrical component 40N arrangement) and/or assembled, a wiring harness connector 60 may be designed and/or manufactured. In embodiments, such as generally illustrated in
In embodiments, at least one connector terminal (e.g., terminal 64) may be configured for an electrical connection with an electrical component that is not attached to circuit board 20 and/or that is not part of a trace minimizing electrical component arrangement. In embodiments, such an electrical component that is not attached to circuit board 20 and/or that is not part of a trace minimizing electrical component arrangement may include a power source, such as, for example, a vehicle battery 80.
In embodiments, a method of manufacturing an electrical connector 60 may comprise determining a footprint (e.g., physical dimensions) and/or layout of a conventional circuit board, which may include determining a conventional total amount of traces 50 that electrically connect a plurality of electrical components 40N. The method may include determining a circuit board layout that minimizes a total amount of electrical traces 50. The minimized amount of traces 50 may be determined according to the same circuit board footprint as the conventional circuit board and the minimized amount be less than the conventional total amount of traces (e.g., a lesser total amount of traces for the same size circuit board or, potentially, a smaller circuit board). The method may include designing a layout for terminals of the electrical connector 60 according to the determined circuit board layout and/or manufacturing, the electrical connector 60 according to the designed layout.
Various embodiments are described herein to various apparatuses, systems, and/or methods. Numerous specific details are set forth to provide a thorough understanding of the overall structure, function, manufacture, and use of the embodiments as described in the specification and illustrated in the accompanying drawings. It will be understood by those skilled in the art, however, that the embodiments may be practiced without such specific details. In other instances, well-known operations, components, and elements have not been described in detail so as not to obscure the embodiments described in the specification. Those of ordinary skill in the art will understand that the embodiments described and illustrated herein are non-limiting examples, and thus it can be appreciated that the specific structural and functional details disclosed herein may be representative and do not necessarily limit the scope of the embodiments.
Reference throughout the specification to “various embodiments,” “some embodiments,” “one embodiment,” or “an embodiment,” or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of the phrases “in various embodiments,” “in some embodiments,” “in one embodiment,” or “in an embodiment,” or the like, in places throughout the specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. Thus, the particular features, structures, or characteristics illustrated or described in connection with one embodiment may be combined, in whole or in part, with the features, structures, or characteristics of one or more other embodiments without limitation given that such combination is not illogical or non-functional.
Although only certain embodiments have been described above with a degree of particularity, those skilled in the art could make numerous alterations to the disclosed embodiments without departing from the scope of this disclosure. Joinder references (e.g., attached, coupled, connected, and the like) are to be construed broadly and may include intermediate members between a connection of elements and relative movement between elements. As such, joinder references do not necessarily imply that two elements are directly connected/coupled and in fixed relation to each other. The use of “e.g.” throughout the specification is to be construed broadly and is used to provide non-limiting examples of embodiments of the disclosure, and the disclosure is not limited to such examples. It is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative only and not limiting. Changes in detail or structure may be made without departing from the present disclosure as defined in the appended claims.
